You can get it from the App Store. It's a small (<8 mb download), but some people over at ehMac.ca are reporting that they were forced to download the entire 10.8.1 rather than just the update. This didn't happen to me. You can read about it from Apple's website here._________________Mini 1 (2012): 2.3 ghz Core i7; 10gb RAM, Corsair 240gb SSD, 500gb Seagate XT
